//cached

maybe rm outbound when req chan close?
like this

move set outbound nil to func

chisel/share/tunnel/tunnel_in_proxy_udp.go

Line 185 in 4eb9e6a

func (u *udpListener) unsetUDPChan(sshConn ssh.Conn) {

func (u *udpListener) unsetUDPChan(sshConn ssh.Conn) {
	sshConn.Wait()
	u.onLoseChannel()
}

func (u *udpListener) onLoseChannel() {
	u.Debugf("lost channel")
	u.outboundMut.Lock()
	u.outbound = nil
	u.outboundMut.Unlock()
}

call onLoseChannel after chan close

go ssh.DiscardRequests(reqs)

go func() {
  ssh.DiscardRequests(reqs)
  // channel done...
  u.onLoseChannel()
}()
